The invention relates to the technical field of automobile safety, in particular to a congestion early warning method and system based on vehicle and road information fusion and a storage medium, and the method comprises the steps: obtaining dynamic traffic data; obtaining traffic parameters based on the dynamic traffic data; performing standardization processing on the traffic parameters to obtain a standard congestion index vector; determining a weight coefficient of the road section where the vehicle is located based on the distance between the road section and the intersection; determining a comprehensive measurement value according to the standard congestion index vector and the weight coefficient; and based on the comprehensive measurement value, the congestion level of the current road section is judged, and congestion early warning is carried out. Multi-source dynamic traffic data are collected, so that the accuracy and reliability of the traffic data are improved; and the characteristic value of the traffic operation state is calculated by using the multi-source dynamic traffic data, the road congestion evaluation index is determined, and corresponding congestion early warning is carried out, so that a reference effect is provided for solving the traffic congestion problem in the future.
